The switch contact 4531 is disposed at one end of the output shaft 452, the switch contact 4531 is at an angle of 90° with the lever 453, and the upper limit switch 458 and the lower limit switch 459 are respectively disposed at Both sides of the lever 453. (Note: In the following embodiments, the setting manners of the upper limit switch 458 and the lower limit switch 459 can be set with reference to the setting mode of the embodiment. To make the drawings in the following embodiments clearer, remove This part of the structure.)

The tea basket 41 described herein is moved together with the carriage 455 by a frame 44 fixed to the carriage 455. The center of the tea basket 41 corresponds to the center position of the teacup 3 and is above the teacup 3. An inner tea basket 42 is disposed in the tea basket 41, and the tea basket 41 and the inner tea basket 42 are respectively provided with a tea basket cover 46 and an inner tea basket cover 43, and the tea basket 41 and the inner tea basket 42 are generally adopted. Made of glass, ceramic, plastic or stainless steel. The bottom and side walls of the tea basket 41 are provided with holes, and the basket of the inner tea basket 42 can be made of a mesh material such as a stainless steel mesh or a plastic mesh to facilitate the filtration and outflow of the tea. The tea basket 41 can be fixed to the frame 44 or can be made into a movable structure, and the inner tea basket 42 must be designed to be easily taken out and conveniently placed in the structure of the tea basket 41, so that it can be easily poured out. The tea leaves that have been soaked in the tea basket 42 are easy to clean.

The inner tea basket cover 43 of the inner tea basket 42 functions to press the tea leaves in the inner basket. Because, after the dry tea leaves are placed in the inner tea basket 42, when the inner tea basket 42 is immersed in the tea cup 3, the dry tea leaves are easily floated in the water, thus affecting the tea making effect. With the inner tea basket cover 43, the tea leaves can be pressed, and as long as the space for the expansion of the tea leaves is left, the tea leaves can be well immersed in the process of making tea. The inner tea basket cover 43 can be made of stainless steel or plastic, and its structure can be used as a flanged structure for the image of the lid, and the flange can be made into an elastic claw structure. Thus, after the inner tea basket cover 43 is pressed into the inner tea basket 42 by hand, the elastic claws can be in close contact with the inner side wall of the inner tea basket 42 by elasticity, thereby playing a relatively fixed role.

The combination of the tea basket 41 and the teacup 3 is such that the frame 44 cooperates with the teacup 3, and the tea basket 41 and the frame 44 may be in a fixed fit or an active fit. The inner tea basket 42 cooperates with the tea basket 41, and the tea basket cover 46 is sealed with the tea basket 41. Therefore, as long as the inner tea basket 42, the tea basket 41, the frame 44, the outer tea basket cover 46, and the tea cup 3 are well matched, the sealing of the tea making process can be basically achieved. In order to seal the tea cup 3 when brewing tea, a silicone ring can be added between the tea basket cover 46 and the tea basket 41, and the frame between the frame 44 and the tea cup 3 to obtain a better sealing effect. .

The bottom of the base 7 is further provided with a storage tank 71, which is mainly used for storing waste tea water, and the waste tea water can also pass through a base shell of the base 7 by connecting a water pipe at the bottom of the storage tank 71. 5 Flow into the bucket of waste tea.

The working principle of the lifting mechanism 45:

As shown in FIG. 3, FIG. 3-1, and FIG. 4, the power of the motor 451 is turned on (assuming that the carriage 455 is at the upper limit position), the motor 451 starts to operate, and the rotation of the output shaft 452 causes The lever 453 rotates 360 degrees. At the same time, due to the rotation of the lever 453, the pulley 454 hinged thereon is laterally moved in the horizontal guide 4551. As the lever 453 rotates, the pulley 454 presses the lower flange surface of the horizontal guide 4551, thereby pressing the carriage 455 downwardly along the vertical guide 456. mobile. When the carriage 455 is moved down to the lower limit position, the switch contact 4531 touches the lower limit switch 459, and the lower limit switch 459 is closed. After the control circuit detects that the lower limit switch 459 is closed, it is determined that the carriage 455 has reached the lower limit position. At this time, the control circuit controls the motor 451 to stop rotating.

If the carriage 455 is required to rise at this time, the control circuit only needs to turn on the power in the motor 451, the motor 451 starts to rotate, and the rotation of the output shaft 452 causes the lever 453 mounted on the motor output shaft to rotate 360 degrees. At this time, the carriage 455 is already in the lower limit position, that is, one end of the lever 453 to which the pulley 454 is hinged has been rotated to the lowest position. If the motor 451 continues to rotate, the end of the lever 453 to which the pulley 454 is hinged can only be rotated upward. . At this time, as the motor 451 continues to rotate, the pulley 454 hinged on the lever 453 presses the upper flange surface of the horizontal guide groove 4551, forcing the carriage 455 to move vertically upward along the vertical guide 456. When the carriage 455 is moved to the upper limit position, the switch contact 4531 touches the upper limit switch 458, the upper limit switch 458 is closed, and the control circuit detects that the upper limit switch 458 has been closed, then it is determined that the carriage 455 has reached the upper limit position. At this time, the control circuit controls the motor 451 to stop rotating, and the carriage 455 is stopped at the upper limit position.

The working principle of this embodiment:

As shown in Fig. 1 and Fig. 2, the preparation work when the user needs to make tea is: first fill the water in the water tank 1; then, select and press the 'tea making' function button to open the tea basket cover 46 and the inner tea. The basket cover 43, the tea leaves are placed in the inner tea basket 42, and the tea basket cover 46 and the inner tea basket cover 43 are covered; secondly, the tea time is selected to be warm and tea time; finally, press the 'start' button, the tea machine Start working and enter the following process stages.

The water adding stage: the electromagnetic valve I23 connected to the water outlet I11 of the water tank 1 is opened, and the water in the water tank 1 flows into the boiling water cup 2 through the electromagnetic valve I23, and the water level detecting device 27 in the boiling water cup 2 detects that the water in the cup reaches the highest level. At the water level A, the control circuit closes the solenoid valve I23 and the water in the water tank 1 stops flowing.

The water boiling stage: the control circuit controls the heating element 25 at the bottom of the boiling water cup 2 to start heating the water in the boiling water cup 2, and the temperature sensor 26 at the bottom of the boiling water cup 2 starts to detect the temperature of the water in the boiling water cup 2, when the water temperature reaches the water temperature set by the user. At this time, the control circuit controls the heating element 25 to stop heating.

The hot water is added to the cupping stage: the control circuit controls the operation of the water pump 24, and the water in the boiling cup 2 is pumped through the line 22 into the cup 3. When the water level detecting means 27 in the water cup 2 detects that the water in the cup is lower than the lowest water level B, the control circuit controls the water pump 24 to stop operating.

Tea-making stage: The control circuit knows that the water level of the boiling cup 2 is a low water level, and it is determined that there is already water in the cup 3, and the control circuit controls the lifting mechanism 45 to work. At this time, the motor 451 starts to rotate, and the lever 453 is hinged with one end of the pulley 454 to press the groove of the horizontal guide groove 4551, so that the carriage 455 moves on the vertical guide 456, that is, when the guide wheel 454 presses the horizontal guide groove 4551 At the lower edge, the carriage 455 moves downward, and the tea basket 41, the inner tea basket 42, and the tea leaves in the inner tea basket 42 are lowered into the teacup 3. When the carriage 455 is lowered to the lower limit position, the switch contact 4531 is moved to the lower limit position switch 459, the lower limit position switch 459 is closed, and the control circuit obtains the signal of the action of the lower limit position switch 459, so that the carriage 455 is stopped at the lower limit position, the tea has been Soak in the water of the cup 3 to start making tea. At this time, the control circuit starts to count the tea time according to the tea time set by the user.

During the brewing of tea, in order to soak the tea leaves in the teacup 3, the mixing and soaking of the tea leaves and the tea is more uniform, and the procedure of raising and lowering the lifting mechanism 45 several times in the control circuit can be added. That is, the lifting mechanism 45 is subjected to a lifting and lowering process of raising and lowering several times, that is, the tea leaves in the inner tea basket 42 are lifted off the water surface and then dropped into the tea water, and the operation is repeated several times to achieve that the tea leaves are more foamed. Full and uniform effect of tea concentration.

Ending the tea making stage: when the brewing time of the control circuit reaches the brewing time set by the user, the control circuit controls the lifting mechanism 45 to work, the motor 451 starts to rotate, and one end of the pulley 454 hinged by the lever 453 presses the horizontal guiding groove 4551 When the upper flange of the groove is moved, the carriage 455 is moved upward in the vertical guide 456, and the frame 44, the tea basket 41, and the inner tea basket 42 fixed on the carriage 455 are raised together, the tea basket 41 and the inner tea basket. 42 leaves the tea in the cup 3. When the carriage 455 rises to the upper limit position, the switch contact 4531 toggles the upper limit position switch 458, the upper limit position switch 458 is closed, and the control circuit obtains the signal of the action of the upper limit position switch 458, causing the carriage 455 to stop at the upper limit position and ending the bubble. tea.

The tea loading stage: when the tea is finished, the control circuit determines whether there is a tea cup 65 by detecting whether the magnetic switch 62 on the cup holder 61 provided on the base 7 is closed, and if the magnetic switch 62 on the cup holder 61 is closed, The cup holder 65 has been placed on the cup holder 61. At this time, the control circuit controls the solenoid valve III33 to open, and the tea flows out of the water outlet III32 of the cup 3 into the cup 65, and when the set solenoid valve III33 is opened, The solenoid valve III33 is closed and the tea water flows out.

In the present embodiment, when the embodiment does not include the susceptor 7, the tea loading stage can be set to a manually controlled mode. That is, when the tea machine displays "the end of the tea making stage - that is, the carriage 455 is stopped at the upper limit position", according to the prompt of the tea machine, the user can control the opening of the solenoid valve III33 (or the water outlet switch) by a manual button. closure.

In the present embodiment, when the embodiment does not include the susceptor 7, the tea loading stage can also be set to the automatic tea control mode. That is, before the tea machine displays "the end of the tea making stage - that is, the carriage 455 is stopped at the upper limit position", the user only needs to press the tea confirmation button, and the control circuit automatically controls after the tea machine displays the tea making stage. Open the solenoid valve III33 to get tea.

Make a 360 degree rotation. Due to the rotation of the lever 453, the pulley 454 articulated thereon and the upper surface of the horizontal flange I4552 fixed on the carriage 455 generate a force. Since the return spring I4555 is provided between the carriage 455 and the lower portion of the bracket 457, the pulley 454 is always in contact with the upper surface of the horizontal flange I4552. At this time, when the lever 453 on the output shaft of the motor 451 continues to rotate, and the pulley 454 hinged on the lever 453 moves downward, the pulley 454 presses the upper surface of the horizontal flange I4552, and overcomes the elastic force of the return spring I4555, forcing the slide. The frame 455 is moved vertically downward along the vertical guides 456. When the carriage 455 is moved down to the lower limit position, the switch contact 4531 touches the lower limit switch 459, and the lower limit switch 459 is closed. The control circuit detects that the lower limit switch 459 has been closed, and determines that the carriage 455 has reached the lower limit position. At this time, the control circuit controls the motor 451 to stop rotating, and the carriage 455 stops at the lower limit position.

If the carriage 455 is required to rise at this time, the control circuit only needs to turn on the power in the motor 451, and the motor 451 starts to operate. The lever 453 mounted on the output shaft 452 is rotated 360 degrees. Since the carriage 455 is already at the lower limit position, the end of the lever 453 to which the pulley 454 is hinged has been rotated to the lowest position. If the motor 451 continues to rotate, one end of the lever 453 to which the pulley 454 is hinged can only be rotated upward. As the motor 451 continues to rotate, the pulley 454 hinged on the lever 453 moves over the carriage 455. At this time, the elastic force of the return spring I4555 presses the bottom edge of the carriage 455, forcing the carriage 455 to move vertically upward along the vertical guide 456. When the carriage 455 is moved to the upper limit position, the switch contact 4531 touches the upper limit switch 458, the upper limit switch 458 is closed, and the control circuit detects that the upper limit switch 458 has been closed, determining that the carriage 455 has reached the upper limit position. To this end, the control circuit controls the motor 451 to stop rotating, and the carriage 455 is stopped at the upper limit position.

Since the carriage 455 is already in the lower limit position at this time, the one end of the pulley 453 to which the pulley 454 is hinged has been rotated to the lowest position. If the motor 451 continues to rotate, the end of the lever 453 to which the pulley 454 is hinged can only be rotated upward. To this end, as the motor 451 continues to rotate, the pulley 454 hinged on the lever 453 presses the lower surface of the fixed horizontal flange II4553 on the carriage 455, overcoming the elastic force of the return spring II4556, forcing the carriage 455 to be vertically guided. The piece 456 is moved vertically upward. When the carriage 455 is moved to the upper limit position, the switch contact 4531 touches the upper limit switch 458, the upper limit switch 458 is closed, and the control circuit detects that the upper limit switch 458 has been closed, determining that the carriage 455 has reached the upper limit position. To this end, the control circuit controls the motor 451 to stop rotating, and the carriage 455 is stopped at the upper limit position.
